How to Change Shares on Companies House

At Towerstone Accountants we provide specialist limited company accountancy services for directors and owner managed businesses across the UK. We created this webpage for people responsible for company filings and statutory records who want clear guidance on Companies House requirements without jargon. Our aim is to help you understand your obligations, avoid filing errors, and stay compliant with Companies House and HMRC.

Changing shares in a limited company is one of those tasks that sounds simple but is often misunderstood. I regularly speak to directors who assume it is just a quick update on Companies House, only to discover later that the paperwork was incomplete, the tax consequences were missed, or the change was not legally effective at all.

Shares are at the core of company ownership. They determine who owns the company, who controls it, who receives dividends, and who benefits if the company is sold. Because of that, changes to shares are tightly governed by company law, even though the Companies House filing itself is relatively straightforward.

In this guide I will explain how to change shares on Companies House in the UK, what changes must be reported, what paperwork must be done first, and the common mistakes I see. I will also explain the tax and legal implications you should consider before making any changes, so you do not accidentally create problems that are expensive to fix later.

What does changing shares actually mean

When people talk about changing shares, they can mean several different things.

Common share changes include:

• Issuing new shares

• Transferring shares from one person to another

• Changing share classes

• Buying back shares

• Cancelling or consolidating shares

Companies House does not control whether you are allowed to make these changes. Its role is to record what has already happened. This is an important distinction.

The legal change to the shares happens first. Companies House is notified afterwards.

Why Companies House needs to be updated

Companies House maintains the public register of company ownership and structure. This information is relied on by:

• Banks and lenders

• Investors

• Solicitors

• HMRC

• Potential buyers

If share changes are not recorded correctly, the public record becomes inaccurate. That can cause issues with funding, sales, disputes between shareholders, and tax enquiries.

Directors have a legal duty to keep this information up to date.

The difference between internal records and Companies House filings

This is where many mistakes begin.

When shares change, there are two parallel processes:

• Updating the company’s internal statutory registers

• Notifying Companies House

The internal records come first. These include:

• Register of members

• Share certificates

• Stock transfer forms or allotment records

Companies House filings reflect what is already recorded internally. Filing without proper internal records does not make the change valid.

Common reasons companies change shares

Understanding why shares are being changed helps determine the correct process.

Typical reasons include:

• Bringing in a new shareholder

• Removing a shareholder

• Rewarding an employee or director

• Raising investment

• Restructuring ownership between founders

• Estate or succession planning

Each of these can have different legal and tax consequences.

Step one, check the articles of association

Before changing any shares, you must check the company’s articles of association.

The articles may:

• Restrict the issue of new shares

• Require shareholder approval

• Give existing shareholders pre-emption rights

• Set rules on share transfers

If you ignore the articles, the share change can be invalid even if it is filed at Companies House.

This is one of the most common errors I see, particularly in companies with bespoke articles or shareholder agreements.

Issuing new shares, how it works

Issuing new shares means creating additional shares and allotting them to someone.

This changes:

• Ownership percentages

• Voting rights

• Dividend entitlements

Internal steps before filing

Before notifying Companies House, you must:

• Obtain director approval

• Obtain shareholder approval if required

• Allocate the shares

• Update the register of members

• Issue share certificates

If the shares are being issued for cash, you also need to ensure the money is paid to the company.

Reporting a share issue to Companies House

Once new shares have been issued, you must notify Companies House.

This is done using form SH01.

Key points include:

• The form must be filed within one month of the share issue

• It shows how many shares were issued and their value

• It updates the company’s share capital

Failure to file SH01 on time can result in penalties and compliance issues.

Updating the confirmation statement after a share issue

Issuing shares does not automatically update the shareholder list on the public register.

The shareholder details are updated via the next confirmation statement.

This means:

• SH01 updates share capital

• Confirmation statement updates who owns the shares

Both steps are required for the public record to be accurate.

Transferring shares, how it works

A share transfer is different from a share issue. No new shares are created.

Instead, existing shares move from one person to another.

This might happen when:

• A shareholder sells their shares

• Shares are gifted

• Ownership is rebalanced between founders

Internal steps before filing

For a share transfer, you must:

• Complete a stock transfer form

• Obtain board approval

• Update the register of members

• Issue a new share certificate

The stock transfer form is a legal document and must be completed correctly.

Stamp duty on share transfers

This is an area that is often missed.

If shares are transferred for consideration over £1,000, stamp duty may be payable.

Key points:

• Stamp duty is charged at 0.5 percent

• It is payable to HMRC

• The stock transfer form must be stamped before the transfer is registered

Companies House does not deal with stamp duty. This is handled separately with HMRC.

Failing to address stamp duty can invalidate the transfer.

Notifying Companies House of a share transfer

Unlike a share issue, there is no specific form for share transfers.

Instead:

• The transfer is reflected in the next confirmation statement

• The list of shareholders is updated

This is why internal records are so important. Companies House relies on what you declare in the confirmation statement.

Changing share classes

Some companies have more than one class of shares, for example ordinary shares and alphabet shares.

Changing share classes might involve:

• Creating a new class of shares

• Converting shares from one class to another

• Altering rights attached to shares

These changes often require:

• Changes to the articles of association

• Special shareholder resolutions

• Careful tax planning

Companies House must be notified of changes to share rights, but only after the legal steps are completed.

Buybacks and cancellations of shares

A company can sometimes buy back its own shares or cancel shares.

This is a complex area of company law and should not be done without advice.

It typically involves:

• Special resolutions

• Solvency statements

• Specific Companies House forms

• Potential tax implications for shareholders

Buybacks are heavily regulated because they reduce company capital.

How Companies House records share information

Companies House records several aspects of share information.

These include:

• Total number of shares in issue

• Aggregate nominal value

• Shareholder names and holdings

• PSC status where thresholds are crossed

It does not record:

• Share prices paid

• Private shareholder agreements

• Dividend arrangements

This means the public record is a summary, not the full picture.

PSC considerations when changing shares

Changing shares can affect who is a person with significant control.

A PSC is someone who:

• Owns more than 25 percent of shares

• Controls more than 25 percent of voting rights

• Has significant influence or control

If a share change alters PSC status, this must be updated promptly.

This is a separate obligation from the confirmation statement and should not be overlooked.

Common mistakes when changing shares

Over the years, I see the same errors repeatedly.

Filing before completing legal steps

Companies House filings do not create legal ownership.

Ignoring the articles

Restrictions are often missed, especially in older companies.

Forgetting stamp duty

This can invalidate transfers and cause problems later.

Not updating PSC records

This can lead to penalties and compliance issues.

Assuming accountants handle everything

Unless agreed, share changes are usually the director’s responsibility.

How long you have to update Companies House

Different filings have different deadlines.

Key deadlines include:

• SH01 within one month of a share issue

• PSC changes usually within 14 days

• Confirmation statement at least once every 12 months

Missing deadlines can result in penalties or strike off action.

Can you change shares online

Most Companies House filings can be done online.

This includes:

• Filing SH01

• Filing confirmation statements

• Updating PSC details

However, the internal paperwork must still exist, even if it is not uploaded.

Do you need an accountant or solicitor

Legally, you do not have to use a professional.

In practice, it is often wise to seek advice if:

• Ownership percentages are changing significantly

• There is money changing hands

• There are family members involved

• Tax planning is important

Fixing share mistakes later is usually far more expensive than doing it properly at the start.

Tax implications to consider before changing shares

Changing shares can trigger tax consequences.

These may include:

• Capital gains tax

• Income tax

• Stamp duty

• Employment related securities rules

Companies House does not assess tax. That responsibility sits entirely with you.

This is why tax advice should be taken before, not after, changes are made.

How I approach share changes with clients

When clients ask me about changing shares, I focus on sequence and clarity.

I always ask:

• Why are the shares being changed

• What does the end result need to look like

• Are there tax consequences

• Are the articles and agreements aligned

Most problems arise from rushing or treating the change as admin rather than a legal transaction.

Final thoughts

Changing shares on Companies House is not just about filing a form. It is the final step in a legal process that affects ownership, control, and value.

When done properly, the process is straightforward. When done badly, it can create disputes, tax problems, and compliance risks that surface years later.

In my experience, the key is understanding that Companies House records what you have already done. It does not approve, validate, or correct your decisions. That responsibility rests with the directors.

If you are planning to change shares, take the time to do it properly. A small amount of planning and paperwork now can save a significant amount of time, money, and stress in the future.
